The report summary read major improvement was necessary in the area of "cleanliness and condition of facilities and building", including having "appropriate layout, ventilation, hand washing facilities and pest control, to enable good food hygiene."

Major improvement was also required in the management of food safety.

Officers noted there was major improvement required to ensure a "system or checks" are in place to ensure that "food sold or served is safe to eat" as well as for "evidence that staff know about food safety".

Improvement is also needed for the food safety officer to have "confidence that standards will be maintained in future."

However the Japanese eatery got given a "generally satisfactory" rating for having "hygienic food handling".

The inspector raised a litany of problems with the restaurant's standards, including dirty surfaces, in the first report.

Following a revisit on October 1, most of the recommendations had been carried out but there were still problems with record keeping around risk assessment and the date labelling of "foods in storage".

How are hygiene ratings worked out?

The Food Hygiene Rating scheme is run by the Food Standards Agency (FSA.)

It is government led and operates across the UK.

The scheme assesses the hygiene levels of restaurants, takeaways, food shops and cafes.

Each establishment is then given a rating out of five based on several factors.

The main aim is to ensure that all food in the UK is safe to consume.

The rankings, which run from zero (urgent improvement needed) to five (very good), are calculated by an Environmental Food Safety Officer using the food law code of practice.

Things taken into account when judging an establishment’s hygiene rating include:

How hygienically the food is handled – how it is prepared, cooked, re-heated, cooled and stored

The condition of the building – cleanliness, layout, lighting, ventilation and other facilities

How the business manages and records what it does to make sure food is safe

What are the ratings?

0 means that urgent improvement is necessary.

1 means that major improvements are necessary.

2 means that improvements are necessary.

3 means that the business was found to be generally satisfactory.

4 means that the business was rated as good on assessment.

5 means that the business was seen as very good.
